Title: Spring shank coulter wheel assembly
Inventor: MCILHARGEY JOSEPH F
IPC: A01B61/04
Filed: 1999-09-22
Abstract: A coulter wheel assembly for mounting to a farm implement having a frame. The assembly includes a vertical shank having a coil spring at substantially its mid-point and upper and lower shank members extending therefrom. The upper shank member is attached to the frame by means of a mounting bracket and the lower shank member is attached to a rotatable hub. A coulter wheel for engagement of the soil is mounted on the hub. The coulter wheel assembly is used, for example, with no-till planting equipment in order to prepare the soil prior to seed introduction. In operation, the coulter wheel rotates along the ground, thereby penetrating the soil, and is permitted to deflect in response to impact with obstructions by means of the coil spring; the coulter wheel then returns to its original path, thereby providing a uniformly prepared soil surface and preventing damage to the coulter wheel assembly or the implement.

Title: Immunotherapy of b-cell malignancies using anti-cd22 antibodies
Inventor: GOLDENBERG DAVID M
IPC: A61P43/00
Filed: 1998-03-17
Abstract: B-Cell malignacies, such as the B-cell subtype of non-Hodgkin's lymphoma and chronic lymphocytic leukemia, are significant contributors to cancer mortality. The response of B-cell malignancies to various forms of treatment is mixed. Traditional methods of treating B-cell malignancies, including chemotherapy and radiotherapy, have limited utility due to toxic side effects. Immunotherapy with anti-CD20 antibodies have also provided limited success. The use of antibodies that bind with the CD22 antigen, however, provides an effective means to treat B-cell malignancies such as indolent and aggressive forms of B-cell lymphomas, and acute and chronic forms of lymphatic leukemias. Moreover, immunotherapy with anti-CD22 antibodies requires comparatively low doses of antibody protein, and can be used effectively in multimodal therapies.
Patent CA-2285518-A1 (CA)
Inventor: DE BOER EVERT
IPC: H04Q11/04
Filed: 1999-10-07
Abstract: The present invention relates to a switching node for use in a synchronous optical network ring, where the ring is transporting data divided into first size blocks, for example OC-192 optical signals, characterized by data blocks of size 192. The switching node includes several primary receive and send connections, for receiving and transmitting inter-ring optical signals divided into second size blocks, for example OC-48 optical signals, characterized by data blocks of size 48. The switching node further includes a secondary receive and send connection for receiving and transmitting intra-ring optical signals divided into first size blocks. A critical component of the switching node is the main controller, responsible for routing incoming intra-ring first size blocks towards a primary send connection. The main controller divides a first size block into smaller second size blocks, observes the second size blocks for the presence of concatenated data and, in the case where there is presence of concatenated data, routes the second size block as a single unit towards the adjacent network ring. In the case where there is absence of concatenated data, the routing controller routes the group of data forming the second size block as independent data elements towards the adjacent network ring.

Abstract: La présente invention concerne un système de transmission conçu de façon à optimiser l'utilisation d'une plage d'émission spectrale d'amplificateurs optiques à fibres dopées aux terres rares. Le système comprend une large bande de canaux dans la plage d'émission spectrale d'amplificateurs optiques à fibres dopées à l'erbium qui est divisée en deux sous-bandes, une sous-bande inférieure correspondant à l'extrémité inférieure de la plage et une sous-bande supérieure correspondant à l'extrémité supérieure de la plage. Les deux sous-bandes sont amplifiées et optimisées séparément, puis à nouveau associées sans compétition significative entre les deux sous-bandes. En outre, on applique à la sous-bande inférieure un filtre d'égalisation tel qu'un filtre de Bragg spécialisé ou un filtre à interférence et non à la totalité de la bande de canaux, ce qui réduit grandement le besoin d'égalisation ou les effets de la non égalisation. Dans un amplificateur de ligne optique du système, on amplifie la bande large dans un premier étage d'un amplificateur à fibres qui fonctionne en mode linéaire, puis la bande large est séparée en deux sous-bandes, et l'une des sous-bandes est amplifiée dans un second étage de l'amplificateur à fibres qui fonctionne en saturation.

Title: Shielded integrated circuit capacitor
Inventor: LINDER WILLIAM J
IPC: H01L21/02
Filed: 1998-08-13
Abstract: An integrated circuit (IC) capacitor offers reduced sensitivity to parasitic capacitance, reduced-size, and increased noise immunity, such as for use in digital-to-analog converters (DACs), analog-to-digital converters (ADCs), switched-capacitor filters, and other IC circuits. The capacitor includes a first polysilicon layer, a superjacent second polysilicon layer separated from the first polysilicon layer by an insulator, and an overlying metal layer separated from the second polysilicon layer by an insulator. The metal layer provides a shield that is connected to a known voltage, or to the first polysilicon layer. When connected to the first polysilicon layer, the overlying metal layer also provides additional parallel capacitance, thereby reducing the integrated circuit area of the capacitor. In one example, the overlying metal layer is a second metal layer that is also used, together with a first metal layer, for interconnecting IC components.

Title: Non-zero minimum cell rate for available bit rate atm service
Inventor: ABE KOHEI
IPC: H04L12/56
Filed: 1998-11-17
Abstract: A schedular in accord with the invention schedules available bit rate (ABR) traffic over an asynchronous transfer mode (ATM) link in such a manner as to provide circuits having the ABR traffic service a minimum cell rate (MCR) that may be greater than zero. The scheduler uses static scheduling information to schedule traffic for high priority services, such as constant bit rate service. The static information also specifies transmit opportunities for an ABR circuit, in a manner analogous to that for CBR traffic. The statically scheduled transmit opportunities provide a negotiated minimum cell rate that is greater than zero, for the ABR circuit. The scheduler maintains dynamic scheduling information, which it uses to schedule traffic in otherwise available transmit times. For example, the scheduler may use the dynamic information to create a work list of virtual circuit connections for ABR service. During any cell transmit time that is not used by a higher priority service (e.g. CBR or MCR), the scheduler goes to the work list to find a circuit with a cell ready for transmission and initiates transmission of the cell for that circuit. The ABR circuit having a non-zero MCR receives service from the statically scheduled opportunities and from the dynamically scheduled opportunities.
